"At least two people were seriously injured in the crash," CNN's Wolf Blitzer reported as the network aired dramatic footage of the rescue.

Blitzer added that officials had informed him that the East River's temperature was about 68 degrees Fahrenheit.

ABC News reported that "three people have reportedly been pulled from shore" and that another person pulled onto a raft by a rescuer "appeared to be unresponsive."

Based on television footage of the scene, the New York Fire Department (FDNY) and EMS and a rescue helicopter were involved in rescue operations. Officials from the Federal Aviation Administration were said to be en route to the scene to investigate the crash.
